3 Claims.

This invention has reference to certain new and useful improvements in wax pots for shoe sewing machines and the object of the invention is to provide a pot of this character which is especially adapted for use on lockstitch sewing machines and which is characterized by simplicity of construction, facility of mounting, and the fact that the amount of wax in the pot may be at all times ascertained at a glance.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure l. is an elevation view of the wax pot.

Figure 2 is a View taken at right angles to Figure 1 and with certain of the parts shown in section.

Figure 3 is a top plan view of the wax pot assembly.

Figure 4 is a bottom plan view of the supporting bracket for the pot.

Figure 5 is a fragmentary sectional view through an eyelet equipped end of a guide plate.

Figure 6 is an elevational View of a thread guide and stripper and guide pulley assembly.

Figure 7 is a fragmentary sectional View through the body plate of the attaching bracket.

Referring to the drawings by reference numerals, it will be seen that the invention consists of a bracket Ill, the same being in the form of a plate II having an attaching flange l2 integral therewith and provided in its edges with notches l3 whereby the bracket may be secured to any suitable part it of a lockstitch or other suitable type of shoe sewing machine through the medium of screws 5.

The plate H of the bracket is provided in its underiace with a circular recess it provided with inwardly extending projections H.

The wax pot proper is indicated by the reference numeral 158 and is in the form of a glass jar having a threaded neck I8 that fits into the recess E6 of the plate H with the threads of the neck engaging the projections il in a manner clearlyshown in Figure 2 to secure the neck within the recess. The top of the jar I 8 is substantially closed through the medium of a disk is of rubber or other suitable material clamped between the neck of the pot and the plate l as shown in Figure 2.

In the region of the recess I6, the plate H in the top thereof is provided with openings accommoda ing pins or reduced projections provided on the lower ends of thread guides and strippers 2G and 2| respectively.

The thread guide and stripper members 20 and 2| consist of externally threaded bodies having sockets in their upper ends accommodating therein stripper blocks 22 secured in position by apertured plugs 23, which are in turn secured in 5 position through the medium of socket nuts 24 threaded onto the bodies or shells of the members 243 and 2!. The nuts 24 are provided with suitable radial sockets 25 for the reception of a suitable tool in screwing the nuts onto the members 28 and 2| or removing the same therefrom.

The member 25 is secured in position through the medium of a bolt 26 that extends through a flange 29a formed integrally with the member 26 and which bolt and nut means also extends through the plate ll.

Associated with the member 2| is a pulley supporting bracket 21 which, as clearly shown in Figure 6 is provided with a base flange disposed under the flange Zia formed integral with the member 2!, and extending through apertures in the base flange of the bracket 21, the flange 2 la, and the bracket plate H is suitable bolt and nut means 28 for securing the members 2i and 21 in position on the plate H of the bracket. Suitably mounted on the bracket 21 is a guide pulley 29.

Disposed vertically within the pot i8 is a thread guide plate 3i! that at its upper end is provided with an attaching flange whereby the 30 bracket is secured'in position through the medium of the aforementioned bolt and nut means 2%. Adjacent its lower end the guide plate 36 is provided with eyelets BI and 32.

In actual practice, a thread 33 leading from 35 a suitable spool is passed down into the pot l8 through one of the openings 34 provided in the plate ii of the bracket, and within the pot I 8 said thread is trained through one of the eyelets, for example, the eyelet 3|, the thread in passing upwardly through a suitable opening provided therefor in the bottom of the member 2! and also through the stripper 22, after which said thread is trained over the guide pulley 29, and from the pulley 29 the thread passes through the various directing devices and finally to the needle or other stitch forming mechanism.

Also in accordance with this invention, a second thread 35 is passed into the wax in the pot l 8 through the other of the opening 3e, and within the jar the second thread is trained through the other eyelet, in this instance, the eyelet 32, then through the guide member 20, the stripper associated therewith and thence over the various directing devices either to the needle or stitch forming mechanism of a second sewing machine, or this second thread may be used solely for emergency purposes in case the first thread should break.

What is claimed is:

1. In combination, a waX pot having a threaded neck, a supporting bracket for the pot having an apertured plate-like portion constituting a cover and provided with a recess equipped with lugs adapted to be en aged by the threads of the neck for securing the pot tothe bracket, the apertures in the bracket plate serving as openings for the thread, and guide means for the thread extending from the bracket into the wax pot, said guide means comprising a plate having an end secured to the bracket and a free end terminating within the wax pot and provided with eyelets for the passage of the thread therethrough, and thread guide and stripper members mounted on the bracket for the passage therethrough of the thread issuing from the wax pot, and a bracket associated with one of said thread guide and stripper members, a guide pulley journaled on the bracket and over which the thread passing through the said one guide and stripper member is trained.

2. A support for wax pots comprising a bracket for attachment to a sewing machine, said bracket including a lateral apertured plate constituting a cover and formed with a recess equipped with lugs on its lower side adapted to receive the threaded neck of a wax pot, the apertures in the plate serving as entrances for untreated thread, a guide means secured to the lower side of the plate Within the cavity and depending therefrom, said lateral plate further formed with a pair of openings, a combined apertured thread guide and stripper member one above the other mounted on top the lateral plate one in each 5 opening, a lateral flange on one of the combination guide and stripper members, an upstanding bracket having an arm secured under the flange, and a guide pulley journalled on the upstanding bracket in alignment with the aperture in the combination guide and stripper by which the upstanding bracket is secured.

3. In combination, a glass wax pot having a threaded neck, an angular supporting bracket having an upright leg adapted for connection to a sewing machine, the lateral leg of the bracket constituting a cover for the wax pot and provided with a recess in which the neck of the wax pot is removably seated, the walls of the recess equipped with lugs engageable with the threads on the neck of the wax pot for detachably securing the wax pot to the lateral leg of the bracket, said lateral leg of the bracket being apertured with-' in the area defined by the cavity to permit threads to enter and leave the wax pot, aper- 5 tured guide means secured to the lower face of the lateral leg within the cavity and depending into the wax pot, and an apertured gripping member secured to the upper face of the lateral leg Within the area defined by the cavity with the aperture therein registering with the aperture in the lateral leg by which the thread leaves the wax pot.
